Paper Abstract

In the development of distributed optical fiber temperature sensors, there is big noise in the measured temperature curve. The noise is caused by the fluctuation of laser power. If the laser power fluctuates more than 5%, then there will be very large noise in the demodulated temperature OTDR curve. A new method called dynamic base line matching is taken to eliminate this noise. The experiment result is quite well
